The AFE5803 is a highly integrated Analog Front-End (AFE) solution specifically designed for ultrasound systems in which high performance and small size are required. The AFE5803 integrates a complete time-gain-control (TGC) imaging path. It also enables users to select one of various power/noise combinations to optimize system performance. Therefore, the AFE5803 is a suitable ultrasound analog front end solution for portable systems.

The AFE5803 contains eight channels of voltage controlled amplifier (VCA), 14/12-bit Analog-to-Digital Converter (ADC). The VCA includes Low noise Amplifier (LNA), Voltage controlled Attenuator (VCAT), Programmable Gain Amplifier (PGA), and Low-Pass Filter (LPF). The LNA gain is programmable to support 250 mVPP to 1 VPP input signals. Programmable active termination is also supported by the LNA. The ultra-low noise VCAT provides an attenuation control range of 40 dB and improves overall low gain SNR which benefits harmonic imaging and near field imaging. The PGA provides gain options of 24 dB and 30 dB. Before the ADC, a LPF can be configured as 10 MHz, 15 MHz, 20 MHz or 30 MHz to support ultrasound applications with different frequencies. The high-performance 14bit/65 MSPS ADC in the AFE5803 achieves 77dBFS SNR. It ensures excellent SNR at low chain gain. The ADC’s LVDS outputs enable flexible system integration desired for miniaturized systems.

The AFE5803 is available in a 15mm × 9mm, 135-pin BGA package and it is specified for operation from 0°C to 85°C. It is also pin-to-pin compatible to the AFE5807, AFE5808 and AFE5808A.
